HOW DOES BITCOIN WORK?
To process Bitcoin transactions, a procedure called “mining” must take place, which involves a computer solving a difficult mathematical problem with a 64-digit solution.
For each problem solved, one block of Bitcoin is processed. In addition, the miner is rewarded with new Bitcoin.
To compensate for the growing power of computer chips, the difficulty of the puzzles is adjusted to ensure a steady stream of new Bitcoins are produced each day.
There are currently about 21million Bitcoin tokens in existence. To receive a Bitcoin, a user must have a Bitcoin address – a string of 27-34 letters and numbers – which acts as a kind of virtual postbox.
These addresses are in turn stored in Bitcoin wallets, which are used to manage savings. The bulk of Bitcoin “mining” is done in China, where energy costs are cheaper than in places like the UK or US.
